Include fixed and proportional transaction costs in the weighted

semi-variance model.

Assume a mixture of (two) normal distributions and write a program that

calculates lower and upper partial moments for arbitrary threshold returns

and moments using numerical integration. Check your results using Monte

Carlo simulation.
